2 Claims.

Thisinvention relates to new and useful improvements in a brick forming machine. Its primary object being to provide means to form a frog in the side of a wire cutbrick.

Depressions or frogs have been. customarily formed in to moulded brick only. The present device provides novel means of gouging out a depression in a wire cut brick which. heretofore has .not been accomplished. The depression or frog as it is called is for. the purpose of preventing the bricks from moving when set in position oefore the mortar is dry. With wire cut bricks )ther means have been devised for this purpose with doubtful success. The principle of these )eing cored or pressed holes through the body of the brick which has its disadvantages in manu- :acture and in loss of strength or weakening of (he brick which is easily broken across the re iuced area portion formed by the holes.

The present invention provides means to form 'rogs inopposite sides of two bricks when passng through the machine on a conveyor belt and means to adjust the depth of the same. These rogs reduce the weight of the finished brick ,nd therefore economize on the amount of clay lsed. As they prevent the brick from slipping et in the soft mortar a brick setter is able to my more bricks than with the ordinary type.

With these and other objects in view that lay appear while the description proceeds, the ivention consists in the novel construction and rrangement of parts as hereinafter more specifally set forth, claimed and shown in the ac- Jmpanying drawings forming part of this aplication and in which:

Figure 1 is a plan view of my invention.

Fig. 2 is a front end view of the same.

Fig. 3 is a side elevation of the machine.

Fig. 4 is a rear end view of themachine.

Fig. 5 is a further plan view showing alterate adjustment means.

Fig. 6 is a sectional view on the line 6-6 of lg. 5.

Fig. 7 is an enlarged detailview on the line of Fig. 5.

Referring more in detail to the drawings in nich similar reference characters designate corsponcling parts throughout the several views will be seen the invention is adapted to be ed with a brick forming machine of the standd manufacture and of the type wherein the icks are formed in a mould and carried in tips on a conveyor belt and cut to size by wires itably arranged with respect to length and dth of the bricks. The device is designed to rowback to back. A

operate on each side of the bricks as they travel on the conveyor belt and consists of a frame member Ill supported above the conveyor belt H whereon the bricks. [2 are carried in a double pair of arms i3 having angular support brackets Ifia are supported on said frame and pivotally a manner to permit lateral movement- On the forwardends I 5 gouge tools iii are adjustably secured by clamp members ll while the rearward ends are provided with cam arms l8 having cam members 18a supported thereon. Said members are arranged to engage arms I!) on the conveyor and are actuated to move outward as the arms engage the same. This causes an inward movement on the forward end of the arm with a reduced travel corresponding to the difference in the lengths of the opposite ends of the arms from the pivotal point.

A retraction spring 20 is connected to the arms and draws them together when the cam action is completed. Adjustable stop members 21 are positioned on the frame It] against which the arms normally rest.

In Figs. 5 and 6 modifications of the several adjustments are shown. The lateral stop adjustments for the arms [3 are carried on a cross member 22 supported on the frame i and consists of set screws 23 threadably mounted in the turned up ends of the member and arranged to engage the arms at a predetermined distance from the centerline. The gouges it are also adjustable vertically on the supports 24 and laterally by the clamps ll to accommodate any variations in size of brick tiles or other articles which may be used on the conveyor belt.

The cam. is replaced with ball bearing structures consisting of supporting arms 25 mounted on the arms I3. A cam shaped frame 2'6 is secured thereto and a plurality of ball bearings 21 is mounted in a ball race 28 which is secured to the frame 26. The balls are arranged to protrude from the race and engage the arms H! of the conveyor and thereby to actuate the arms I 3, with a minimum of friction or wear to either the cam. device or the actuating arms.

From the foregoing it will be seen that the arms carrying the gouges will be actuated at regular intervals corresponding to the travel of the conveyor and the length of a brick thereon as arranged by the position of the arms IS. The

.cam device is also arranged to hold the gouges in engagement with the brick for a predetermined period corresponding to the length of frog it is desired to make. The device as thus set mounted on pins. M, in

forth when used in combination with a standard wire cutting brick machine will form the frog as stated in one side of each brick. v

It is believed that the construction and advantages of the structure shown may be apparent from the foregoing paragraphs taken in conjunction with the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed it is understood that minor changes'in the details of construction, combination and arrangement of co-operating elements may be resorted to within the scope of what is claimed without departing from the spirit of the invention.

I claim: I 1. In a brick making machine, the combination of a conveyor belt for carrying a column of clay, a frame mounted above said belt including a transverse bar, a pair of arms pivotally mounted intermediate their ends to the transverse bar above said conveyor to swing in a plane parallel to the plane of said conveyor belt,said arms being disposed one on each side of the column of clay, gouging tools mounted on one end of said arms adapted to be moved into and out or engagement with the column of clay", resilient means normally holding saidarms to disengage said gouging tools from the column of clay, cam

- including atransversebar, aspair of arms members on the opposite ends of said arms, and means carried by said conveyor belt at spaced intervals adapted to engage said-cam members to actuate said arms intermittently to move said gouging tools into operative engagementwith the clay column.

2.'In a brick making machine, the combination of a conveyor belt for carrying a column of clay, a frame mounted above said conveyor belt pivotally mounted intermediate their ends to the transverse bar above said conveyor belt to swing in a plane parallel to the plane of said conveyor -belt, said arms being disposed one on each side of the column of clay, gouging tools mounted on theforward ends of said arms, a spring connecting said arms adapted to swing said arms to move said gouging tools away from the column of clay, adjustable means attached to the trans- I verse bar of said frame for limiting the swinging movement of said arms, cam members carried by. the rear ends of said arms, and posts extending a upwardly from said conveyor belt at spacedine. tervals adapted to contactwith said cam meme bers for intermittently swinging said arms to move said gouging tools into operative engage-,7

ment with the column of clay.
